[0023] The present invention provides an explosion-proof device for chemical safety. Figure 1-5As shown, the explosion-proof device for chemical safety includes: a base plate 1, with an explosion-proof box 2 fixedly mounted on the top of the base plate 1; an explosion-proof door 3 that can be controlled to open and close, and the explosion-proof door 3 is arranged on the explosion-proof box 2; a movable assembly rack 4, and the assembly rack 4 is arranged in the explosion-proof box 2; a placement seat 5, the placement seat 5 is fixedly mounted on the assembly rack 4, and a plurality of storage tanks 6 are arranged on the placement seat 5, and the storage tanks 6 are used to hold chemical raw materials; an adjustment mechanism for driving the assembly rack 4 to move, and the adjustment mechanism is arranged on the explosion-proof box 2; a control mechanism for regulating the opening and closing of the explosion-proof door 3, and the control mechanism is arranged on the explosion-proof box 2.

[0024] In this embodiment, the base plate 1 serves as the foundation of the entire device. The base plate 1 ensures the stability and structural integrity of the explosion-proof box, can bear the weight of the explosion-proof box 2 and the internal devices, and at the same time provides additional support during explosion prevention to reduce the impact of the impact on the ground; the explosion-proof box 2 is the core structure, and its internal space is large enough to accommodate the assembly rack 4 and the storage tank 6; the explosion-proof door 3 is used to seal the entrance of the explosion-proof box 2, has good sealing performance, prevents external fire sources or chemicals from entering, and at the same time, when the internal pressure is too high, it can safely release the pressure through the pressure relief pipe at the bottom; the assembly rack 4 can move freely inside the explosion-proof box 2, and the position of the storage tank 6 can be adjusted by the adjustment mechanism to enter and exit the explosion-proof box 2, which is convenient for the storage and management of chemicals.

[0025] In a further preferred embodiment of the present utility model, the adjusting mechanism includes: a first screw 7 rotatably mounted in the explosion-proof box 2, the first screw 7 threadedly passing through the assembly frame 4; a first guide rod 8 fixed in the explosion-proof box 2, the first guide rod 8 passing through the assembly frame 4; a mounting shell 9 fixed to the explosion-proof box 2; a motor 10 disposed in the mounting shell 9, the output shaft of the motor 10 and the first screw 7 are respectively fixedly mounted with first bevel teeth 11 and second bevel teeth 12, and the first bevel teeth 11 are meshed with the second bevel teeth 12.

[0026] In this embodiment, a first screw 7 is rotatably mounted within the explosion-proof box 2, and its threaded portion extends through the assembly frame 4. When the first screw 7 rotates, the assembly frame 4 moves axially along the first screw 7 due to the interaction of the threads. By rotating the first screw 7, the assembly frame 4 and the storage tank 6 thereon can be precisely adjusted in position, improving the flexibility of storage and retrieval. Furthermore, this mechanical transmission method is stable and reliable, capable of withstanding heavy loads. A first guide rod 8 is fixed within the explosion-proof box 2 and extends through the assembly frame 4. It serves as a guide for the movement of the assembly frame 4, ensuring that the assembly frame maintains linear motion during movement and preventing deviation or shaking. The introduction of the first guide rod 8 improves the smoothness and accuracy of the assembly frame's movement and reduces the safety risks that may be caused by deviation or shaking. It also shares some of the weight of the assembly frame and the storage tank thereon, reducing the load on the first screw 7. A mounting shell 9 is fixed to the explosion-proof box 2, providing a mounting platform for the motor 10 and other transmission components. It protects the internal components from the influence of the external environment, and also facilitates the maintenance and inspection of these components; the design of the mounting shell 9 improves the integration and compactness of the entire adjustment mechanism, making the entire device more beautiful and easy to manage. At the same time, it also improves the reliability and service life of the transmission components; the motor 10 is installed in the mounting shell 9, and its output shaft is connected to the first bevel gear 11 on the first screw 7 through a transmission device. When the motor is started, its output shaft will drive the first bevel gear 11 to rotate, and then drive the second bevel gear 12 and the first screw 7 to rotate through a meshing relationship; the introduction of the motor 10 realizes the automatic control of the adjustment mechanism, improving the convenience and efficiency of operation. At the same time, it also reduces the risk and labor intensity of manual operation; the first bevel gear 11 is fixed to the output shaft of the motor 10, and the second bevel gear 12 is fixed to the first screw 7. The two realize power transmission through a meshing relationship. When motor 10 is activated, first bevel gear 11 rotates second bevel gear 12, which in turn drives first screw 7 and assembly frame 4. By integrating components such as first screw 7, first guide rod 8, mounting housing 9, motor 10, first bevel gear 11, and second bevel gear 12, precise position adjustment of the assembly frame and the storage tank on it is achieved. This design not only increases the flexibility of storage and retrieval, but also enhances the safety and reliability of the entire device.

[0027] In a further preferred embodiment of the present invention, the control mechanism includes: a second screw 13 rotatably mounted in the explosion-proof box 2; a threaded sleeve 14 threadedly sleeved on the second screw 13, one end of the threaded sleeve 14 being fixedly connected to the explosion-proof door 3; a sleeve block 15 fixed on the threaded sleeve 14; a second guide rod 16 slidably mounted on the sleeve block 15, the second guide rod 16 being fixedly connected to the inner wall of the explosion-proof box 2; an assembly block 17 fixed on the explosion-proof box 2, a transmission shaft 18 for transmission being rotatably mounted on the assembly block 17; a third bevel gear 19 and a fourth bevel gear 20 fixedly mounted on the transmission shaft 18 and the second screw 13, respectively, the third bevel gear 19 being meshed with the fourth bevel gear 20; a gearbox 21 fixed on the explosion-proof box 2, the output shaft of the gearbox 21 being fixedly connected to the transmission shaft 18 via a coupling, and the input shaft of the gearbox 21 being fixedly connected to the output shaft of the motor 10 via a coupling.

[0028] In this embodiment, a second screw 13 is rotatably mounted within the explosion-proof housing 2, while a threaded sleeve 14 is sleeved onto the second screw 13, one end of which is fixedly connected to the explosion-proof vent 3. As the second screw 13 rotates, the interaction of the threads causes the threaded sleeve 14 to move the explosion-proof vent 3 axially along the second screw 13, thereby opening or closing the explosion-proof vent. This design makes control of the explosion-proof vent simple and straightforward. By controlling the rotational direction and speed of the second screw 13, the degree and speed of opening of the explosion-proof vent can be precisely controlled, improving operational flexibility and safety. A sleeve block 15 is fixed to the threaded sleeve 14, while a second guide rod 16 is slidably mounted on the sleeve block 15 and fixedly connected to the inner wall of the explosion-proof housing 2. This forms a stable guide system, ensuring that the threaded sleeve 14 maintains linear motion during movement, preventing deviation or shaking. An assembly block 17 is fixed to the explosion-proof housing 2, and a drive shaft 18 is rotatably mounted on the assembly block 17. The third bevel gear 19 and the fourth bevel gear 20 are respectively fixed to the transmission shaft 18 and the second screw 13, and achieve power transmission through a meshing relationship. When the motor 10 is started, the power is transmitted to the transmission shaft 18 through the adjustment of the gearbox 21, and then the second screw 13 is driven to rotate by the third bevel gear 19 and the fourth bevel gear 20. At the same time, the introduction of the gearbox 21 allows the power transmission to be adjusted as needed, improving the adaptability and flexibility of the control mechanism. By introducing the second screw 13, threaded sleeve 14, sleeve block 15, second guide rod 16, assembly block 17, transmission shaft 18, third bevel gear 19, fourth bevel gear 20 and gearbox 21 and other components, precise control of the explosion-proof door 3 is achieved.

[0036] In this embodiment, a detachable explosion-proof inspection panel is added to the explosion-proof box 2, and screws and temperature and humidity detectors are integrated on the inspection panel. This design not only facilitates the daily maintenance and inspection of the explosion-proof box, but also realizes real-time monitoring of the internal environment of the explosion-proof box, thereby improving the safety and reliability of the equipment.

[0037] To sum up, the precise position adjustment of the assembly frame 4 and the storage tank 6 thereon is achieved through the adjustment mechanism composed of the first screw 7, the first guide rod 8 and the motor 10. This design not only improves the flexibility of storage and material retrieval, but also speeds up the operation speed and reduces the risk and labor intensity of manual operation; the design of the explosion-proof box 2 has sufficient internal space and good sealing to prevent external fire sources or chemicals from entering.
